Analysis of Neurogenic Disordered Discourse Production

Implementation of discourse analysis in aphasia: investigating the feasibility of a Knowledge-to-Action intervention

“…Agnes's Western Aphasia Battery diagnosis of anomic aphasia, a non-fluent impairment characterised by breaks in fluency associated with difficulties with word retrieval (Potagas, Kasselimis, & Evdokimidis, 2017). Goals and therapy approaches targeting these features were also observed with high frequency, consistent with the expectation that therapy would target the most pervasive features of impairment (Kong, 2016).…”

Main Concept Analysis for Acquired Deficits of Spoken Narratives: Preliminary Data on Inter-rater Agreement and Potential Application to the Korean-Speaking Population

“…Six MCA indices were applied to the language samples, which were crosschecked to determine discrepancies of results across raters. The present results were con-review in Kong [1]). One of them is the measurement of main concepts [3], which is a propositional-based analytic system that focuses on the quantification of presence, accuracy, and completeness of essential information in spoken narratives in PWAs.…”

“…The mutual influence of these various layers of performance can be identified with refined discourse analysis [12]. According to Kong [1], "the process of translating spoken data to an orthographic medium involves the making of multiple decisions along the way"… and … "the degree of how many decisions are made by an examiner in preparing and processing a transcript and how reliable these decisions are will depend on factors such as the type of the discourse tasks, experience of preparing transcription and conducting text-based discourse analyses on the part of the raters, and the nature of the actual analyses (p. 66)". Although the analytic procedures of the MCA were claimed to be straightforward and clinically-friendly [5,7,10], inter-rater agreement of transcript coding (and subsequent MCA scoring) seemed to be affected by factors such as examiners' familiarity of narrative analysis or, simply, the test itself.…”

“…Aphasia is a type of acquired language disorder in adults as a result of a cerebrovascular accident (i.e., stroke) or traumatic brain injury (TBI). People with aphasia (PWAs) or adults with TBI demonstrate impairments in language production, such as reduced content and lexical diversity, syntactic complexity, impaired cohesion and coherence [1]. Discourse level analysis of oral production by PWAs is informative of their microand macro-linguistic analysis.…”

Cantonese AphasiaBank: An annotated database of spoken discourse and co-verbal gestures by healthy and language-impaired native Cantonese speakers

“…In addition, the tagger can handle situations in which two morphological processes have taken place-for instance, prefixation and suffixation: 兔 Brabbit^➔ 兔仔 Brabbit + diminutive^➔ 阿 仔 Bendearing + rabbit + diminutive^; or prefixation and reduplication: 妹 ➔ 妹妹 Bsister^➔ 小 妹 Blittle + sister,^掉轉 Bturn around^➔ 掉轉頭 Bturn around + suffix^➔ 掉翻 頭 Bturn around + aspect marker insertion + suffix. nnotating spoken output of PWA One of the greatest challenges of annotating an aphasic speech output corpora is the potential disagreement of parsing POS in the nonfluent or grammatically ill-formed sentences of PWA. As is detailed in Kong (2016), unifying the linguistic information, paralinguistic aspects of oral production, and nonverbal skills co-occurring in spoken narratives can be a daunting task, due to the complexity of this phenomenon. This is especially the case when output is produced by language-impaired people.…”
